It seems that the editor wanted to have as many pages in this booklet, so he could call it a book, that he could muster. Large type, small pages, and liberal use of white space still couldn't get it even to 100 pages. The editor even started counting at the title page, so by the time you get to chapter 1, you're already on page 21. I guess the editor took some of the lessons from the authors, about how to rip-off the customers, to heart. I don't read very fast, and spent less than two hours to completely study this novelette.
The authors try and convey a image of rampant rip-offs by a single waiter being possible, but I just don't believe that the scale of their implications are possible. There are a few good scams that may be possible, such as recycling customer checks, but any decent restaurateur has these beat with a good point of sale system, and security cameras.
The references to how bartenders rip-off the customers and store were extremely weak, and probably thrown into the book"let" in order to claim that area is covered. I seriously doubt that the authors ever worked behind the bar, or even interviewed any bartenders before writing this book. For example, they say the bartender should short pour to rip-off his customers. What good is that going to do the bartender? They don't pay for the liquor, the owner does. If anything, over pour so you get larger tips. Duh! Remember, the owner is paying for it, and a customer appreciates and rewards a bartender pouring heavy.
At $12.95 the book is overpriced. It would be appropriately priced around $3.95, provided you always received free shipping. So, for the Amazon rating, if you took $12.95 and divided it by 5 stars, each star is worth $2.59. ($3.95 value / $12.95 cost) * 5 stars) = 1.53 Amazon stars, and we round up to 2 (plus I'm feeling pretty generous right now).
On the positive side, I like the concept of the book, and would like to read one that is more detailed, accurate, and covers more real life situations.
